Unmarked but certainly German (Henckels?) 3.75” boning knife. The carbon steel blade has been skillfully thinned from a slightly larger (5”?) blade that had been sharpened down, it does not have the geometry or feel of a sharpened down knife but most likely is.
The European walnut handle is secure and tight with no problems.
3 3/4” 8 5/8” overall length
